Brief report: additive and subtractive counterfactual reasoning of children with high-functioning autism spectrum disorders.
Kids with HFASD grow toward subtractive "if only I hadn't" thinking, while typical peers grow toward additive "if only I had" thinking—plan social-problem teaching accordingly.
01Research in Context
What this study did
Begeer et al. (2009) asked kids to think about "what could have been." They compared children with high-functioning autism to same-age peers.
Each child heard short stories about social mishaps. Then they said how things might have ended better.
What they found
Typical kids moved toward "I should have added" thoughts as they grew. Kids with HFASD moved toward "I should have removed" thoughts.
The two groups were heading in opposite directions. This split showed up even though both groups had similar IQ scores.
How this fits with other research
Morsanyi et al. (2012) later saw the same HFASD teens fail when the stories were fantasy. They kept treating pretend facts as real.
Naito et al. (2020) and Hsieh et al. (2014) tracked younger HFASD kids. They found early gaps in future planning and source memory.
Together the papers trace a line: early memory and planning gaps may feed into later counter-factual differences.
Why it matters
If you teach social problem-solving, note the child's style. A child who thinks "I should have stayed home" needs different prompts than one who thinks "I should have spoken up." Try shaping additive scripts: "What else could you add next time?" Use visual supports and role-play so the new script feels concrete, not imaginary.

03Original abstract
The development of additive ('If only I had done...') and subtractive ('If only I had not done....') counterfactual reasoning was examined in children with High Functioning Autism Spectrum Disorders (HFASD) (n = 72) and typically developing controls (n = 71), aged 6-12 years. Children were presented four stories where they could generate counterfactuals based on a given consequent (e.g., 'you left muddy footprints in the kitchen. How could that have been prevented?'). Children with HFASD increasingly used subtractive counterfactuals as they got older, but controls showed an increase in additive counterfactuals, which may be linked to their growing adaptive and flexible skills. Children with HFASD likely develop different strategies for their counterfactual reasoning. The role of IQ and ideational fluency will be discussed.
